Does "acoustic fabric" really exist? At Sontext, we receive weekly inquiries from designers who want to know, "We need sound-absorbing panels for our project—how do we know if the fabric we want to use is suitable for Acoustic Panels?" It's a great question and one that highlights some confusion in the industry.

While some fabric or textile manufacturers label their materials as "acoustic," it's essential to understand what this means. Just because a fabric is marketed as "acoustic" does not necessarily mean it will perform well in terms of sound absorption. Often, fabrics considered "acoustic" may only be intended as a decorative covering on Acoustic Panels rather than contributing to the panel's acoustic properties. Certain fabrics could even reduce the effectiveness of the sound-absorbing material inside the panel.

So, what should you look for when choosing a fabric or textile for an Acoustic Panel? The most important consideration is whether the fabric allows air to pass through easily. This is key to ensuring that the fabric is acoustically transparent. When air flows freely through the fabric, sound waves can reach the absorbing material inside the panel, helping to improve the panel’s overall sound absorption performance.

The technical term for this property is Flow Resistivity, and it's a key factor in determining how suitable a fabric is for acoustic applications. Some manufacturers provide this information on their product data sheets, which can be helpful when deciding. While visually striking, fabrics like suede or leather are not breathable—they don’t allow air to pass through, which means the sound-absorbing insulation inside the panel won't be as effective. These materials can also disrupt the sound dynamics that reach the panel's surface. In some cases, however, these fabrics can be perforated to allow for better airflow, but this should always be done cautiously.

Suppose you're considering a particular fabric for your project. In that case, it’s always advisable to consult with Sontext or an acoustic engineer before finalizing your choice. Some textiles are specifically designed to assist with sound absorption, especially when installed over an air gap. Still, proper installation is crucial for these products to perform well. Working with an expert ensures you’re making the right choice for your space's aesthetic and acoustic needs.

In summary, when selecting a fabric for acoustic wall or ceiling panels, it's essential to ensure its suitability for sound absorption. Check the fabric’s specifications with the supplier or consult your local Sontext distributor to confirm its performance. Taking these steps will ensure that the fabric meets your design requirements and supports the acoustic performance of your panels, helping you create a better sound environment.
